A Model of Magnetohydrodynamic Domains for a Nematic with a Negative Anisotropy of Diamagnetic Susceptibility

Observation by optical polarization microscopy of test particles (spacers) embedded in a nematic layer with negative diamagnetic susceptibility placed in a magnetic field has shown that there is no movement of particles in the realized torsion geometry. In this regard, a model of magnetohydrodynamic domains describing the motion of a nematic fluid with negative diamagnetic susceptibility in the geometry of splay distortion has been considered.
